How a chemical hook borrows a week of half-life
The single most interesting thing about CJC-1295 is not what it does at the receptor, but how the DAC version lasts so long. DAC stands for Drug Affinity Complex: a tiny reactive group that grabs albumin, the most abundant protein in blood, and rides its natural longevity. A peptide that would normally clear in minutes suddenly persists for the better part of a week.
This unit walks that trick step by step: the maleimide-albumin bond, why albumin lives so long, how the recycling system keeps it around, and why continuous binding produces continuous receptor stimulation. It is a clean, worked example of a strategy used across modern drug design.
